Implementing computer aided design in small businesses

The lack of real and speedy success in the implementation of Computer Aided Design (CAD) in small firms has been a cause for concern for the author for some years. Whilst much has been written about the implementation of Management Information Systems and about Advanced Manufacturing Technology in large firms, the literature on small firms is very sparse, and the implementer has nowhere to go for guidance. This research looks at the implementation of CAD in six small firms against the background of the current literature in associated areas. It focusses on the aspects of implementation most commonly featured in the implementation texts, developing some 32 Propositions on the basis of the six cases.A review of the propositions suggests a parallel between their sequence and what may be regarded as a "traditional" business plan, which addresses the questions:- where are we now? - where do we want to go?- how do we plan to get there?- what steps must we take?- how will we know when we get there? The link between the propositions and the structure is strong, and the consequence is clear. If the propositions indicate a structure, then a structure developed specifically to incorporate the propositions should result in a methodology for implementation. The framework for this methodology is developed, based upon five phases or stages:- strategy- company audit- design- action- review. The framework has been tested and amended, and the inputs to the phases have been identified. Sources for these inputs have also been specified where necessary. The framework provides a significant step forward in the understanding of Computer Aided Design implementation in small firms. In particular:- it is constructed using "hard" data- it provides guidance on a "best" way of implementing- it forms the basis of an implementation "toolkit"- it addresses the needs of the small firm, which can least afford specialist help and can least afford failure.
